Tardigrade anatomy [3]. Tardigrades have a short plump body with four pairs of hollow unjointed legs. Most range from 0.1 to 0.5 mm (0.004 to 0.02 in) in length, although the largest species may reach 1.3 mm (0.051 in).
Tardigrades can withstand 1,000 times more radiation than other animals, [17] median lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) in hydrated animals (5 to 10 Gy could be fatal to a human). [18] Earlier experiments attributed this to their lowered water content, providing fewer reactants for ionizing radiation. [18]
Tardigrades, or water bears, thrive in some of Earth’s harshest environments. Now, researchers say they have unlocked the survival mechanism of the tiny creature. Scientists now think they know ...
Dsup (contraction of damage suppressor) is a DNA-associating protein, unique to the tardigrade, [1] that suppresses the occurrence of DNA breaks by radiation. [2] [3] When human HEK293 cells were engineered with Dsup proteins, they showed approximately 40% more tolerance against X-ray radiation.
Tardigrades inhabit a variety of lichens and mosses. They need water in these areas to allow for gas exchange and to prevent them from desiccating. [5] Because of this they are considered aquatic. However, they have also been found in all types of environments, ranging from the deep sea to dunes. [5]
Chinese military scientists believe the tardigrade’s cells improve a human's ability to withstand radiation and potentially other diseases.
Ramazzottius is a genus of water bear or moss piglet, a tardigrade in the class Eutardigrada, named after the Italian zoologist Giuseppe Ramazzotti.. Ramazzottius varieornatus (see image) is a terrestrial invertebrate that is extroardinarily tolerant of extreme conditions such as irradiation, chemicals, dehydration and high pressure. [2]
